First, here's a whole picture to shock you. In fact, this picture is based on [url=https://bbs.eeworld.com.cn/viewthread.php?tid=417805&extra=page%3D1&frombbs=1]Measuring resistance, there are only tw...
When I split the ground plane in protel, I punched the vias for DGND and GND, and a green highlight appeared on the edge of the via. Is that an error message? Also, after the power plane is split, the...
In CE, when the font (such as Xingkai) is directly output to the system DC, it has anti-aliasing, but when it is output to the self-created memory DC, there is no anti-aliasing. . . ....
Recently I used benq's m23 and found that I can use at$simtest to detect whether the SIM card is connected. The return value is 1 if it is detected, and 0 if it is not detected. Now I want to use TR80...
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
A multi-point temperature control heating control system was designed using the SST89E564RC single-chip microcomputer and a new temperature measuring device. The heating system can be controlled in...[Details]

High-precision current source can provide high-precision current supply for precision instruments, and is suitable for automatic measurement tasks of various resistors in semico...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
Direct digital frequency synthesis (DDS) has fast frequency switching and modulation capabilities and is widely used. However, when low power consumption and low cost are the main considerations, D...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
